You can begin to hear it around 40. lasts for a few seconds then stops. Only occurs with cold start. Just wondering if anyone knew what this might be. Thanks!

 

AH man mine started doing that last night too. Sounds very similar to mine as well and only happens on a cold start.

Did you ever find out what it is? I actually did a quick recording of mine this morning, sorry didn't realize it was recording vertically...
